For the APPROX setting, numerical integration is tried first, if applicable. Anti-derivatives are sought only where such numerical integration is inapplicable or fails. ‰() can be nested to do multiple integrals. Integration limits can depend on integration variables outside them. Note: See also nInt(). ‰(e^(ë x^2),x,ë 1,1)¥ ¸ 1.493... ‰(‰(ln(x+y),y,0,x),x,0,a) ¸ ‡() (square root) 2 ] key ‡ (expression1) ⇒ expression ‡ (list1) ⇒ list Returns the square root of the argument. For a list, returns the square roots of all the elements in list1. ‡(4) ¸ ‡({9,a,4}) ¸ 2 {3 ‡a 2} Π( ) (product) MATH/Calculus menu Π(expression1, var, low, high) ⇒ expression Evaluates expression1 for each value of var from low to high, and returns the product of the results.
